Most of the particles went through the foil, but some were deflected
That the mass of an atom is mostly located in a small nucleus.
The conclusion was that an atom has a nucleus (center) with a positive charge.

This classic diffraction experiment was conducted in 1911.
he shot tiny alpha particles throug a piece of gold foil.
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.
That the mass of an atom is mostly located in a small nucleus.
The conclusion was that an atom has a nucleus (center) with a positive charge.
It is the result of the experiment. It is the value of the observation.
You call it an OBSERVATION.
